Luna Park Cafe, an outdoor seasonal concession south of the pavilion at the parks north end, has had a good run. The restaurants early boosters, including Rob Walsh, former head of the Union Square Business Improvement District, said it brought safety to the park at night. Under the plan to renovate the parks north end, the cafes location will become an expanded playground. The pavilion will be renovated to host a seasonal private restaurant and a request for proposals will be issued for the project and restaurant.
